| 3593 | 首先，综合考虑社交媒体文本中用户之间的提及关系、用户对位置指示词的提及关系和用户对地理名词的提及关系，构建包含用户、位置指示词和地理名词 3 种节点的异质网络； | First, a heterogeneous networkwas constructed by comprehensively considering the mention relationship between users, the user's mention relationshipwith location indicative words, and the user's mention relationship with geographic nouns. |
| 3594 | 其次，基于共同提及关系提出用户−词语−位置简化算法来构建用户−位置异质网络，将位置邻近的用户更为紧密地联系起来； | Then, a network simplificationstrategy was proposed to construct a user-location heterogeneous network that connects users live nearby more closelybased on the common mention relationship. |
| 3595 | 再次，提出有偏的随机游走算法对图中节点采样以充分探索网络结构，缓解已知位置的稀疏性问题； | After that, a biased random walk algorithm was proposed for the graph nodesampling to fully explore the network structure and alleviate the sparsity problem of known locations. |
| 3596 | 最后，采用基于多层感知机的神经网络分类器对用户进行位置推断。 | Finally, a neuralnetwork classifier based on a multilayer perceptron was used to infer the user's location. |
| 3597 | 在 GEOTEXT、TW-US 和TW-WORLD 这 3 个代表性 Twitter 数据集上的实验结果表明，所提方法可显著提高用户位置推断准确率。 | Experimental results on threerepresentative Twitter data sets of GEOTEXT, TW-US and TW-WORLD show that the proposed method can significant-ly improve the user geolocalization accuracy. |
| 3598 | 为提高数据访问流转控制的透明性、访问流转的可溯源，提出了一种基于区块链的可溯源访问控制机制。 | To improve the transparency and traceability of access control, a blockchain-based access control mechanismfor data traceability and provenance was proposed. |
| 3599 | 所提机制将访问控制策略以智能合约的形式部署在区块链上，通过执行分布式的智能合约实现访问控制策略的评估，确保整个访问授权过程的无中心、透明性和可溯源； | The proposed access control policy was transferred to the smart con-tract and deployed on the blockchain, and the access authorization evaluation was realized by executing the smart con-tract deployed on the blockchain to ensure the decentralization, transparency and traceability of the access control process. |
| 3600 | 采用链下和链上相结合的方式，将客体存储在链下数据服务器，通过客体存储地址和摘要值等信息生成客体索引存储在客体区块链上； | The manner of combining off-chain and on-chain was adopted, the object was stored in off-chain data server, and the ob-ject index was generated by the object storage address and hash value, and deployed on the object blockchain. |
| 3601 | 日志区块链详细记录了客体访问授权过程和访问过程，任何错误行为都不可修改地记录在区块链上。通过安全性分析，所提机制在保证客体资源隐私性的前提下，实现了访问授权无中心、透明性和可溯源。 | The log of object access authorization and access were recorded in the log blockchain, any misbehavior was immutably recorded.The security analysis show that, the proposed mechanism achieve the properties of decentralization, transparency andtraceability while ensuring the privacy of data. |
| 3602 | 为了满足宽带通信的发展需求，提出了一种基于相干双光频梳的微波光子信道化接收机，所用的光频梳仅需一个双平行马赫−曾德尔调制器就可生成，平坦度高，外带抑制比高，自由谱范围灵活可调，并且有效简化了接收机的复杂程度。 | In order to meet the future development needs of broadband communications, a microwave photonic channeli-zation receiver based on dual coherent optical frequency comb (OFC) was proposed. The used optical frequency combcan be generated by only a dual parallel Mach-Zehnder modulator (DPMZM), which not only has high degree of flatnessand out band rejection ratio, flexible and adjustable free spectrum range, but also effectively simplifies the complexity of the receiver. |
